There are more combinations than Alt-Tab that Windows will trap. For
example on my pc if I do

  (global-set-key [(super ?e)]
       (lambda() (interactive) (message "called super E")))

This does not work, lwindow+e will still show Windows Explorer.

That is correct according to MS documentation which says you can not
rely on rebinding lwindow/rwindow without a low level keyboard hook.
Sometimes it works, sometimes it doesn't.
